When members of Enterprise Admins are in a child domain (or at least I think so), I get the error:

Get-ADUser : A referral was returned from the server.

How do I force AD to retrieve the user object details for the child domains?

You're probably going to have to enumerate the users and get their home domains, and send the requests to those domains. Get-ADUser picks a domain controller in your logon domain, by default, and that can't resolve user requests for other domains' users. Parameters of the command let you target different domains.
